CONSTRUCTION OF FIRE-EXTINGUISHER TANKS.

Specification of Letters Patent.

Patented May 18, 1909.

To all whom it may concern:

Be it known that I, GEORGE F. FIFER, a citizen of the United States, residing at Providence, in the State of Rhode Island, have invented a new and useful Improvement in the Construction of Fire-Extinguisher Tanks, of which the following is a specification.

The nature of my invention consists in an improved construction whereby the curved discharge pipe 01" the tank may be made removable instead of being permanently soldered to the head of the tank as heretofore, and a stronger oint be provided between the said pipe and the head of the tank.

In the accompanying drawings :Figure 1 represents a vertical axial section of the fire extinguisher tank, Fig. 2, represents a transverse section taken in the line 2, 2, of Fig. 1. Fig. 3, re resents an enlarged side view of the removab e curved discharge pipe of the tank. F 4:, re resents an enlarged side view of the flanged sleeve which is secured to the hemispherical head of the tank. Fig. 5, represents a detail top view of the discharging end of the tank.

In the drawing, A represents a cylindrical fire extinguisher tank provided with the hemispherical heads B and C, and with the opening D through which the receptacle for holding the acid for producing the gas is inserted, the said opening being then tightly closed by means of a suitable cover,

To the inner side of the hemispherical head B, is secured the sleeve E, by means of the oblique curved flange F, which is firmly riveted to the inner side of the head B, and The sleeve E is provided with the stuffing box M, by means of which a tight joint is formed around the removable discharge pipe G, the said discharge pipe being provided at its outer end with the valve H, and with the hose attaching pipe I, and at its closed inner end with the perforations J. The perforated end of the said pipe is removably held in osition by means of the retaining checks K, soldered to the inner side of the tank at each side of the pipe G as shown in Fig. 2 to prevent the said pipe from turning in the stuffing box M7 The pi e G is provided with a projecting shoulder N at its side in order to hold the said pipe in proper position in the chamber oi the tank.

lNhenever it is desired to remove the dis-- charge pipe from the tank, the valve H is to be first removed from the said pipe together with the gland L of the stufiing box M, then the said discharge pipe G may be withdrawn from the sleeve E and removed through the opening D in the body of the tank.

As heretofore constructed the discharge pipe G has been soldered direct to the head B, and has not been removable, hence the manifest difiiculties of making repairs, and by the employment of the flanged sleeve a much stronger joint is made between the said pipe and the hemispherical head of the tank.

I claim as my invention The combination of a cylindrical fire extinguisher tank provided with hemispherical heads, with a sleeve having an oblique curved flange secured to the hemispherical surface of one of the said heads, the stuffing box in the bore of the said sleeve, a removable discharge pipe passing through the said stufling box and curved to the opposite side of the chamber of the tank, and means for chocking the inner end of the said discharge pipe to prevent turning movement of the said pipe within the said stuffing box.

GEORGE E. FIFER.
